The Ceres summary was discarded, so a solve that diverged or aborted left its
last iterate in psi and that tilt was written onto the partiality of every
reflection of the crystal. Restore the tilt the crystal came in with and stop
refining it; the scale fit alone is still a usable model, which is what the
other three early returns in this function fall back to.
